The Wacker Neuson Throttle Return Spring is a genuine OEM component designed for MG10 series portable generators and GS8003G, GS8000G, and GS10003G generator models. As a factory-sourced part, it is manufactured to the exact specification of the original, ensuring correct spring tension and reliable throttle response right out of the box. This spring is confirmed to fit multiple regional variants across the MG10 and GS8000G/GS10003G lineups, making it a straightforward, direct-fit replacement for a wide range of Wacker Neuson generator configurations.
Key Features
- Correct Spring Rate for Throttle Control — Manufactured to OEM tension spec, so the throttle plate snaps back consistently and holds the correct idle position without hesitation or flutter.
- Direct-Fit OEM Replacement — Drops into the original mounting position with no adjustment needed; engineered to interface with the factory throttle linkage geometry on covered models.
- Broad Generator Fitment — Compatible with MG10-AF, MG10-CL, MG10-LA, MG10-CN, and MG10-ME portable generators, as well as GS8003G, GS8000G, and GS10003G generator models across CE, LA, and CN variants.
- Consistent Engine Speed Recovery — A properly functioning throttle return spring allows the engine to return to governed idle smoothly after load changes, protecting against over-speed and rough running caused by a sluggish or broken spring.
- Fuel System Safety Relevance — A failed or weakened throttle return spring can leave the throttle partially open, creating an uncontrolled throttle condition; replacing it promptly with the correct OEM part restores safe, predictable engine response.
- Genuine Wacker Neuson Part — Sourced directly through Wacker Neuson's OEM supply chain under part number 5000408922, giving you confidence in material grade and dimensional accuracy.
The throttle return spring is a small but critical component in the engine's throttle control system. Its job is to pull the throttle plate or linkage back to the idle position whenever the operator releases throttle input or the governor reduces fuel demand. When this spring weakens, breaks, or loses tension, the throttle may stick open or respond sluggishly, causing erratic engine speed, difficulty idling, and potential over-revving under light or no load. Replacing a worn throttle return spring restores predictable governor response and smooth engine operation.
